(H.)thelma and the nymphs of H. (G.) maculipennis and N. ehrhardti are described for the first time. Three new species, Hermanella (H.) guttata, Hermanella (G.) grandis, and Hylister plaumanni, are described. Eggs of these genera are described and illustrated, and keys to the nymphs and imagines and biological notes are presented.
